We Make Our Shapes To Fit Your Shapes

Whether your tastes are traditional or contemporary, every TrimLine Decorative Window is made to compliment your imagination and design. And, regardless of the size, shape or style, every TrimLine window is individually handcrafted from the finest materials and with energy efficiency in mind.

Trapezoidal units are manufactured with jambs made to any wall thickness.

Choice of all wood or maintenance free clad exteriors.

Unit size and exterior casing is manufactured to line up for use over virtually any size or style double-hung or casement window or door unit.

Frame – All parts are 6/4 kiln dried western pine which are treated with a water repellent preservative and can be painted or stained as desired to complement the individual interior design and style. The basic jamb is a full 4 9/16′, however, any desired wall thickness can be accommodated without the use of extension jambs.

Cladding – The frame cladding is designed so that each TrimLine decorative window can be installed individually or mulled to other TrimLine single or multi-lite casement, awning or double hung window units. The insulating qualities of an interior wooden jamb provide a positive thermal break while being fitted to a low maintenance extruded aluminum exterior frame in a choice of four colors.

Glazing – All units are direct-set glazed with insulating glass up to 1 ¼” in overall thickness. All insulating glass is manufactured using SuperSpacer® which has the lowest thermal conductivity of any edge-seal on the market today increasing the overall R-value by up to 30%. Low E, various tinted and other specialty glass as well as tempered or safety glass is also available.

Glazing Stop – All units are glazed from the inside with decorative wood stops for ease in glass replacement.

Nailing Fin – The aluminum exterior frame is designed to accept a snap-in heavy gauge vinyl flange, which surrounds the entire unit perimeter serving as both an installation fin and window flashing.
